The cylinder has a barrel pivotally coupled to the housing and a rod which extends and retracts with respect to The barrel. The debris guard includes a body of flexible material filling a space between the barrel and the wall of the housing and preventing debris from entering the space.

The body of flexible material is bonded to a surface of the barrel and to the wall of the housing. The flexible material is molded and comprises a closed cell elastomeric material.
